The circuit boards that control the tailights had a recall. See if that has been done. A dealership can tell you. For more info visit our enthusiasts website at

The brake light is on because there is a problem with the brake system. Until the problem is fixed the light will remain on. Once the problem is corrected the light will reset itself.
The antilock brake system has a problem. The light will remain until it is fixed. The abs will not function when light is on. Take it to your mechanic soon.
The ABS module has detected a problem with the ABS system. Until the problem is fixed the light will remain on. As long as the light is on the ABS function will not operate if needed. Have a trusted mechanic diagnose the problem soon.
i have the same problem i replaced the coolant temp sensor to get my check engine light to go off but it could be a number of things the brake light means you have a problem with the brake system but i have hared that the light sticks and is a common problem with blazers in the late eighties and early nineties models
When the ABS and E-Brake dash lights illuminate together, it usually means that there is a loss of pressure. It's a fairly common problem on 4wd S-series vehicles (S-10, Sonoma, Blazer, Jimmy). It's best to have a dealership or qualified repair center diagnose the exact cause and make repairs.
Directly above the brake pedal.
If the brake light fuse is good and the brake light bulbs are good it's probably a faulty brake light switch.
Check the brake fluid level, it may be low. Check brake pads for wear. Light is designed to come on when the brakes are worn. the brake light flashes when there is a problem with the ABS. that flashing is a code...get a cheap code reader from wal mart that has a switch on it for ECU and ABS codes...the book that comes with it will help you diagnose your problem
If the fluid is full then you have an electrical, or switch problem. You will need to have a service manual if you are going to diagnose yourself.
If nothing is holding the pedal down then the brake light switch is at fault.
Well what do you know I solved the mystery mmyself it turns out after I paid to replace wheel cylinders and hoses and bleeding the brakes the cure was an $8.00 brake switch. Once I changed the switch the flashing brake light monster went away. So to anyone else who has a flashing brake light problem with your 89 Chevy S10 Blazer if you get a code 10 that is when the brake warning light flashes 10 times the fix is a new brake switch hope this helps someone.
you can find the switch on the back of the brake pedal.
